付けにより固定されている。In FIG. 1, a gas-liquid separator 1 has two pipes 3 and 4 connected to a sealed container 2 of a hermetic rotary compressor inside the gas-liquid separator 2. The gas-liquid separator 1 completely vaporizes the low-pressure refrigerant sucked from the suction pipe 5 and supplies the liquid to a compression chamber 9 formed by a main bearing 6, a cylinder 7, and a sub-bearing 8 which are compression elements in a closed vessel. It functions to prevent refrigerant from being sucked in and prevent liquid compression. The cylinder 7 is provided with two suction holes 10 and 11 for guiding the low-pressure refrigerant gas from the gas-liquid separator to the compression chamber. The two tubes 3 and 4 in the gas-liquid separator 1 are
2 and 13 are inserted into two suction holes 10 and liners 14 and 15 which are press-fitted into the suction holes 11 in the cylinder 7, and are fixed by brazing.
